Background:
12 years ago I was talking to my parents my mom said:" Kazue you are going to be crowned queen in 2 weeks I said to my mom" that is not fair what about me!? She said, "well the oldest gets to be crown first then you are next to don't be selfish". I was jealous then I made a plan I was going to disturb Kazue ceremony then I walk out of my clan territory I went to the human land when I hid my ears and tail I said to them" I want to join the holy knights" they agreed with me.2 Week Later I told them the Neko clan is planning something to kill the holy knights they were shocked when they said" ok show me the clan place" when we went to the place my ears and tail went the knights attacked killing 2,000 Neko with my little brother and my parent I saw my sister crying and freaking out I kinda felt bad when I saw my sister getting yelled at and getting blame she is running away to save herself.  When my leader said" we're good now let's get back now" My stomach turn I felt like murder and I betrayed my clan I wanted to cry but I can't. 2 days. Later when I saw my sister getting arrested she gave me an angry look I felt like a jerk when Meliodas came he took her in and created Eight Deadly sins. Still should I apologies or should I not? Anyways she was going to be crown queen and I want to be king.  (I wrote full backstory. I will edit later so get excited!)
